Polarization-Maintaining Fiber Optical Patch Cable - PM405

These polarization-maintaining fiber optic patch cables are terminated on both ends with high-quality, narrow key, ceramic FC/PC connectors, featuring high-quality polish with a typical return loss of 50 dB. Each cable is individually tested to ensure the specified extinction ratio and insertion loss at fiber-to-fiber junctions. Each patch cable includes two protective caps that shield the ferrule ends from dust and other hazards. Each cable comes with a mating connector adaptor for ease of use. Fiber Optic Connector Power Handling Thresholds vs Wavelength The line below is an empirical approximate optical power handling for ceramic ferrule connectors vs wavelengths. Operating above this level, the fiber connector butt coupling becomes less reliable.
